I'll post pics. Realize that what I'm calling 'side-arm" style heat exchangers on my boiler mains are functioning as pre-heaters. They heat the water coming from the well. The syphon, or gravity loop connected to my boiler's coil is doing most of the work.
The water comes from the well, and goes through the sidearm on the boiler's return, then jumps over to the sidearm on the boiler's supply. The water from well then goes down to the tee at the bottom, of the tank. From there it goes into the bottom of the tank, AND through the coil, and back to inlet in the side of the tank. Prior to the change, the water from the well ran only into the normal top inlet of the elec tank, and the gravity loop heated the water parked in the tank. That piping routing is shown in the Nov 19th post. Prior to that change, when water was drawn, it went directly into the normal top inlet in the tank. Now, the water enters the tank through either [both side inlets on the tank. None enters the normal top inlet.
